Popis: | e18708 Background: The COVID-19 pandemic has caused shifts in terms of cancer management, but the impact of this has not been well-elucidated in a contemporary cohort of patients in clinical practice in the US. We hypothesized that closure of operating rooms would increase the use of neoadjuvant therapy (NT) during the early pandemic period. Methods: The nationwide Flatiron Health database is a longitudinal electronic health record (EHR)-derived database, comprising de-identified, patient-level structured and unstructured data, curated via technology-enabled abstraction. These data originated from approximately 280 cancer clinics. We compared patients diagnosed with non-metastatic breast cancer during the early pandemic period (March 1 – June 30, 2020; group 1) with those diagnosed in the four month period prior (November 1, 2019 – February 29, 2020; group 2) and those diagnosed during the same period one year earlier (March 1 – June 30, 2019; group 3). Results: There were 174 patients in group 1, 277 in group 2, and 348 in group 3. Overall, 591 (74.1%) were ER/PR+HER2-, 100 (12.6%) were HER2+, and 106 (13.3%) were triple negative (TN). Patients in the three groups were equally likely to be ER/PR+HER2- (75.3% vs. 72.2% vs. 74.9%, p = 0.68), HER2+ (12.1% vs. 14.9% vs. 11%, p = 0.33), TN (12.6% vs. 12.7% vs. 14.2%, p = 0.83) and to be high risk by genomic testing (either Oncotype Dx or Mammaprint; p = 0.72). While there was no difference in the clinical stage (p = 0.36) nor patient age at diagnosis (p = 0.76) across the three groups, patients diagnosed during the early pandemic (group 1) were more likely to receive NT compared to those diagnosed one year earlier (group 3); 28.7% vs 16.4%, p < 0.01 (see table). The use of NT differed between the three groups in the ER/PR+her2- (p < 0.01) and her2+ patients (p = 0.05), but not in the TN patients (p = 0.61). There was no difference in the use of NT overall during the pandemic by geographic state (p = 0.32) nor practice setting (p = 0.23); NT was also similar by geographic state and practice setting when considering the ER/PR+HER2-, HER2+, and TNBC subsets. Conclusions: Despite similar clinicopathologic features as earlier time periods, there was an increased use of NT during the early pandemic when compared to the same period in the prior year. This was seen particularly in the ER/PR+HER2- group, suggesting an increased use of neoadjuvant endocrine therapy.[Table: see text] |
